Hi Conrad
? Don't forget these are metric wire sizes. The size listed will be a 1/2 size larger or smaller than standard sizes. I forget right off the cuff. I think?adding a 1/2 size to the stated number makes them the correct diameter.
??? ?Ron N..hey... didn't' you post these wire sizes once upon an e-mail? They are different than standard. 
? I once re-strung an Identical piano... 1976 C-7 (7 ft 4 inches) and raised each wire a half size. It made it darker sounding & less free sounding. I liked it better before for what it's worth.? Still a beefy sounding piano. I'd vote for new bass strings.
? Jus Wired for sound
??Dale

Duh..., dain bread Friday afternoon.
Smaller wire/lower tension/lower inharmonicity

Anyway,
I won't be able to scale the bass (or anything else), until I get the
plate back in and can measure lengths.
